On the morning of July 15, 1410, the two armies faced off on the fields near Grunwald. The Polish-Lithuanian army, numbering between 30,000 and 50,000 troops, was composed of a diverse coalition of Polish knights, Lithuanian light cavalry, and Tatar allies. Opposing them were the forces of the Teutonic Order, numbering around 15,000 to 20,000 soldiers, including heavily armored knights and mercenaries from across Europe.
The battle began with an intense cavalry charge by the Lithuanian forces, which was initially repelled by the well-trained Teutonic Knights. However, this early phase of the battle was a clever strategy by the Polish-Lithuanian leadership, as the retreating Lithuanians drew the Teutonic forces into a vulnerable position.
As the battle raged on, the Polish forces, led by King Władysław Jagiełło, launched a decisive counterattack. The turning point came when the Polish knights, bolstered by reinforcements, broke through the Teutonic lines. Grand Master Ulrich von Jungingen was killed during the fighting, dealing a crushing blow to the morale of the Teutonic forces.
By the end of the day, the Teutonic Order’s army was defeated, with thousands of knights and soldiers killed or captured. The Polish-Lithuanian victory at Grunwald was total, marking one of the most significant military defeats of the Teutonic Order in its history.
